We love to praise linux constantly and tell everyone to change to it (they should) but what are your biggest annoyances ?
Mine would be, installing software (made even more complex by flatpaks being added, among the 5 other ways there already were to install software) and probably wifi power management issues.
Not what I’m saying at all. KDE has this as a known issue they aim to fix. Gnome only solved it with the move to Wayland and a lot of work on unification of the graphics libraries to render those things.
